Is the secret menu unlock the same on all BMWs? Adding up the last 6 digits to unlock?

The temp should be hitting as high as 90C and should maintain above 75 even when lightly loaded. Mine is dropping as low as 65 when coasting and never got above 77.

The cluster is the same. I think menu 19 to unlock and 7 for temps (IIRC).

If it's running too cold, it won't regen and will cause emissions errors.
It also kills your glowplugs and fuel mileage.
